First things first: The Audi Sport Quattro Concept is brilliant. Attractive, bold, and packing a walloping 700 horsepower from a hybrid driveline, the machine is everything you'd expect from a Frankfurt Motor Show concept. Audi cooked up the Sport Quattro in just five weeks, primarily to show off what's possible from the automaker's driveline department.

There's a twin-turbo 4.0-liter V8 engine under the hood good for 560 horsepower and 590 pound-feet of torque. There's an electric disc motor good for 295 pound-feet of torque stuck between the engine and an eight-speed tiptronic gearbox. The motor can propel the car 31 miles on pure electric power thanks to a liquid-cooled 14.1 kWh lithium-ion battery.
